Sport nutrition, diet or
food and drink, for football players is becoming increasingly scientific
and recognised for its importance in the game of football. Almost every
professional club will have a nutritionist or similar expert advisor for
their team. This article covers the most important principles of sport
nutrition for amateur players and coaches.
Why is sport
nutrition or diet important in football?
-
Food provides us with
energy for our muscles, brain and other organs. Football requires plenty
of exercise, and therefore it is important to have energy available to
us during the game. The energy available to us at any particular time
depends on our blood sugar levels.
-
If we over-eat, we
become over-weight. The heavier we are, the more work our muscles have
to do to take us the same distance. This reduces our stamina, and our
ability to accelerate quickly. If we under-eat, we can become weak and
our overall health can decline, because we are not getting enough
nutrients.
-
A healthy diet
improves our general level of health, and can help us recover more
quickly from injuries.
-
Along with a program
of fitness training, our diet can help us develop stamina and improve
athletic performance.
-
Diet is essential for
our growth, and development.
What to eat and when to eat it
The timing of
the meals you consume is important. On the day of a match the intake of
fat and protein should be restricted, as these nutrients require a
relatively long time to be digested. Plan to have your pre-competition
meal 3-4 hours before the match. Your pre-competition meal should be: high
in carbohydrate (this is the fuel that your body needs to perform at the
highest level), low in fat, low in protein, low in fibre, not too bulky,
and easy to digest. You should consume foods such as: breakfast cereal
with low fat milk, toast or bread with jam/honey, sandwiches with
banana/honey/jam, pasta/rice with low fat sauce, muffins, baked potato,
fruit, energy bars, and orange juice.
A snack high
in carbohydrate may be eaten about 2 hours before the match, however the
time reference is only a guideline as there are great individual
differences in the ability to digest food. It is a good idea for you to
experiment with a variation of foods at different times before training
sessions. Foods such as toast, bread or crumpets with jam/honey, sweetened
cereal and low fat milk, muffins, orange juice and jelly sweets could be
consumed.
Once the game
is over, fluids should be replaced and carbohydrate should be consumed as
soon as possible to promote recovery of glycogen stores. During
the cool down you should consume fluids and small snacks, such as jelly
sweets, jaffa cakes and jammy dodgers. As soon as possible you
should aim to consume a meal which is high in carbohydrates. Foods such as
pasta, spaghetti, rice, noodles, low fat pasta sauce, bread, potatoes, and
baked beans should be consumed during this period.
Carbohydrate
rich foods must be the main source of your diet. Table 1 lists foods,
which contain a lot of carbohydrate. You should aim to consume the main
bulk of your diet from complex carbohydrates. Simple carbohydrates should
not be consumed in large quantities and are more useful as snacks between
workouts, or to top up your energy intake. The carbohydrate you consume
should be balanced with a healthy intake of protein, low fat and plenty of
fruit and vegetables.

If you
do not consume enough carbs (kcals/energy), then you will not have enough
energy to complete the match (or training) and subsequently your
performance will suffer, and more importantly you will be more susceptible
to injury.
Fluids
We’ve done
good food and we’ve looked at what snacks can boost the body during and
after a match or training session. Now lets look at what you should drink.
The water lost
from the body during sweating needs to be replaced to stop you getting
tired quickly, and also speed up the recovery process – that means feeling
fitter and sharper afterwards a lot sooner.
These checks
will help players:
* Weight – 1kg
of weight lost during a training session is equal to 1 litre of fluid
lost.
* The ‘pee test’ – If your urine is dark coloured, it means you need to
have a drink. Lots of trips to the toilet, producing lots of clear
coloured urine, shows you’ve taken on enough fluid.
* Thirst – Being thirsty is an unreliable indicator of when you need to
have a drink. If you’re thirsty, you’re actually already partly dehydrated
so if you finish a training session and you’re gasping it’s a giveaway you
haven’t taken enough fluid on board.
What's
best to drink?
For
footballers, the best fluid to drink is a diluted carbohydrate/electrolyte
solution. In plain English, that’s the kind of stuff you’ll find in stuff
like Isostar, Lucozade Sport and Gatorade.
When
should I drink?
Ideally, it’s
best to drink before, during and after a training session, as well as
drinking frequently during a match.
How
much should I drink?
Only a little
– but often. If you drink too much too quickly, you run the risk of
getting a stomach upset. |
